Mitch,

I am going to see if I can get a custom made one with low restriction and 1 1/4 ports made. I just sent back a boxster front radiator with the 7/8ths ports. I am hoping that the small amount of sq inches extra should be the answer. If not then there is something else wrong. The car runs smooth and is a blast to drive. Long highway runs are the only issue at higher speeds...
